I was driving at night and saw a bright saucer shaped object moving very rapidly from right to left across the sky.

I was driving to pick up my son and saw a very bright object in the sky. At first I thought it might be part of a control tower, but then it started moving, and I saw the saucer shape of the object. There was a strip of flashing lights around the bottom of the spacecraft. It was moving from right to left in the sky, and was larger and brighter than an airplane in another part of the sky. It was also travelling much faster than the airplane. When I picked up my son I told him what I saw, and he started making fun of me because he thought I was crazy. Once I pointed it out to him in the sky, still travelling very rapidly, he believed me. The object was moving away from us, so we drove in the direction it was going. After a few minutes, it was on the horizon, and finally it disappeared from sight.
